java - 如何使用 Junit 5 测试 Spring Boot Rest 控制器

Question

我很难找到关于如何为 Sprint Boot 实际编写 Junit5 测试代码的一致资源。现在，我有一个非常简单的控制器并尝试进行 Junit5 测试，但我什至无法从简单的休息调用中获得结果。假设返回一个字符串值数组。我认为主要问题是 MockHttpServletResponse 标头没有在其中附加端口，但我希望它可以动态添加，因此无论谁拉下代码，Junit5 都可以对其进行测试。

@RestController
public class CnlLetterController {

    
    @Autowired
    private CnlLetterService cnlLetterService;

    @Autowired
    private UserService userService;
    
    @Autowired
    private ServiceLetterService serviceLetterService;
    
    @GetMapping("/rest/cnl/templates")
    public List<String> findTemplates () {
        
        return cnlLetterService.getTemplates();
    }

    /* Other methods that don't matter right now */
}

测试控制器

@ActiveProfiles("dev")
@ExtendWith(SpringExtension.class)
@WebMvcTest(CnlLetterController.class)
class CnlLetterControllerTest {

    @MockBean
    private ClientRegistrationRepository crr;
    
    @MockBean
    private CnlLetterService cnlLetterService;
    
    @MockBean
    private UserService userService;
    
    @MockBean
    private ServiceLetterService serviceLetterService;
    
    @Autowired
    private MockMvc mockMvc;

    @Test
    void testFindTemplates() throws Exception {
        
        mockMvc.perform(MockMvcRequestBuilders.get("/pis/rest/cnl/templates")
                .accept(MediaType.APPLICATION_JSON))
                .andDo(print()).andExpect(status().isOk());
        
    }
}

Junit控制台输出
